my car has been sitting for a while and i just took it out for a spin today.. i have been having a low idle problem for a while but when i started it up it was at 1500 .. after driving it for about 2 minutes i stopped at a stop sign and saw the idle was actually sitting at around 900 for once.. i drove it around some more and when i got home and parked it the idle was sitting down very close to the governor once again.. when the idle is that low it makes it hard to take off without stalling an its starting to get at me.. i was thinking about adjusting the idle screw on the tb but i dont see why it could be at 1500 and just drop so low.. any help??
